from Michael Russo of Russo's Rants,

Wild leading scorer Zach Parise has been diagnosed with a concussion, coach Mike Yeo confirmed this morning.

Not a surprise since Parise looked off his last few shifts against the Pittsburgh Penguins and suddenly didn't come out for the third period even though there was no clear incident to draw from.

According to a few people in the know, Parise did have lingering effects from the stick to the face he got in New York five games ago Oct. 27. He played through it though (quite well, too, against Boston and Dallas especially) because he wasn't sure he had a concussion. Finally, trainers got involved Tuesday night.

Whatever symptoms Parise had were exasperated bigtime with three checks he took against Pittsburgh, folks say. On his first shift, he was bowled over from behind by Roberto Bortuzzo. That definitely seemed to jar him and catch him off guard. In the second period, he got bumped off his skates in the d-zone by Blake Comeau on that shift that ended up 5:44 in with a Comeau penalty and then late in the period Parise got checked into the boards/glass by Kris Letang.
